Navitas Partners with NVIDIA for Cutting-Edge Power Solutions
Navitas Semiconductor, recognized as a front-runner in power semiconductor technologies, has taken a monumental leap by teaming up with NVIDIA to innovate the next generation of 800 V high voltage direct current (HVDC) architecture. This partnership aims to meet the increasing power demands in data centers that support AI workloads, creating a robust foundation for scalable and efficient energy distribution.
Understanding the Need for 800 V HVDC Architecture
In today's fast-paced technological landscape, the rise of artificial intelligence has necessitated dramatic improvements in data center architecture. Conventional systems, which typically operate on 54 V power distribution, face limitations as demand for processing power surges. By shifting to an 800 V HVDC framework, NVIDIA aims to enhance efficiency, reliability, and reduce infrastructure complexity, paving the way for advanced AI computational capabilities.
The Current Landscape
Existing data centers are constrained by outdated systems that utilize bulky copper busbars to transmit low-voltage electricity. As power demands escalate beyond 200 kW, the inefficiencies inherent in these traditional architectures come to the forefront. One of the most pressing issues is the physical limitations of transferring power through copper, which becomes increasingly challenging with higher demand.
The Advantages of 800 V Systems
By adopting a direct 800 V HVDC architecture, power can be delivered with significantly lower current, which minimizes losses associated with resistance in copper wires. This design allows for a reduction in the thickness of copper needed, with estimates suggesting a decrease of up to 45%. Notably, switching to this architecture means less copper usage, which is especially critical for future-proofing technologies in the face of soaring energy needs.
Navitas' Role in Advancing Power Technology
Navitas is positioned as a leader in contributing cutting-edge solutions through GaNFast™ gallium nitride and GeneSiC™ silicon carbide technologies. These innovations are crucial for enabling efficient power delivery from the grid right to the GPUs used in NVIDIA’s systems, such as the Rubin Ultra.
